SANJUAN-RAYGOZA, R.J.  e  JASSO-GASTINEL, C.F.. Effect of waste agave fiber on the reinforcing of virgin or recycled polypropylene. Rev. Mex. Ing. Quím [online]. 2009, vol.8, n.3, pp.319-327. ISSN 1665-2738.

The capability of agave fiber (Tequilana Weber) as a reinforcing agent for polypropylene is studied, using a coupling agent to improve polymer-fiber interaction. Composites using virgin, reprocessed or recycled polypropylene were prepared at different fiber concentrations. Henequen fiber instead of agave fiber was used to prepare other composites as reference. Stress-strain behavior, flexure and falling dart impact testing, were followed to evaluate composites performance. Mechanical response and SEM micrographs show the benefit obtained by the use of coupling agent.
